FREDERICK BASON, OF CHICAGO, ILLINOIS.

RADIATOR.

SPECIFICATION forming part of Letters Patent No. 575,515, dated January19, 1897.

Application filed May 9, 1896.

To all whom it may concern:

Be it known that I, FREDERICK BASON, of Chicago, in the county of Cookand State of Illinois, have invented a new and Improved Radiator, ofwhich the following is a full, clear, and exact description.

The object of this invention is to provide a superior radiator in whichboth steam and water is used, forming an apparatus capable of useexclusively as a steam-heater or exclusively as a-water-heater or withpart of each. In attaining this end I may employ a radiator having aseries of connected loops, vertical steam leading pipes extendingthrough a numberof the loops and having open upper ends, a steam-feedpipe communicating with the steam-leading pipes and also havingcommunication with the loops of the radiator, whereby steam may beadmitted to the radiator either directly to the loops or through thesteam-leading pipes, and whereby also any amount of. water may beretained within the loops, causing the radiator to be exclusively awater-heating apparatus or a part water and part steam heater.

The invention will be fully described here inafter, and its scopedefined in the claim.

Reference is to be had to the accompanying drawings, which illustrate aspecies of my invention and which form a part of this speci fication, inwhich similar characters of reference indicate corresponding parts inall the figures. 1

Figure l is a vertical longitudinal section of my invention. Fig. 2 is across-section thereof on the line 2 2 of Fig. 1, and Fig. 3 is a planview of the connections for the radiator in Figs. 1 and 2.

The loops 15 may be of the usual construc tion, they being incommunication with each other at each end and supported by legs 16. Anair-discharge valve 17 commands an orifice in the upper end of one loop.Formed in the lower rear portion of all of the loops, excepting the endloops, are a series of vertically-extending openings into which elbows18 are screwed. Each elbow has screwed into its vertical upper portion asteam-leading pipe 19, such pipes extending upwardly through the rearsection of each respective loop, the upper ends of the pipes terminatinga short distance below the open upper ends Serial No- 590,839. (Nomodel.)

of the loops. The elbows 18 are each turned forwardly and arerespectively provided with right and left hand threaded thimbles 20. Thethimbles 20 extend transversely with the radiator and are connected to apipe 21 by means of unions 22. The end thimbles 20 are respectivelyconnected by Ts 23 with a pipe 24 and a pipe 25. The pipe 24 extends toa valve 26, in turn communicating with a pipe 27, while the pipe 25 isconnected to a valve 28 by means of an elbow 29. The valve 28 controlsan opening into one of the end loops of the radiator, and the valve 26controls the pipe 27.

WVith the radiator constructed as above de scribed the opening of thevalve 26 and the closing of the valve 28 will permit the steam to passthrough the leading-pipes 19 and be discharged from the open upper endsthereof, the valve 17 having been previously opened to permit the escapeof the air within the radiator. As the steam condenses within the.radiator the water of condensation settles in the lower portion thereofand gradually rises until, as shown in the drawings, it reaches thelevel of the upper ends of the pipes 19. The passage of the steamthrough the pipes 19 keeps the water hot, and in this way the radiatoris made to heat exclusively by hot Water. The surplus water ofcondensation returns through the leading-pipes 19, past the valve 26,and out via the pipe 27.

To convert the radiator into a part steamheater, the valve 28 will beopened, whereupon the water within the radiator will be withdrawn.Supposing now that the water is half withdrawn, it will be seen that thesteam still heats the water, and the steam in the upper portion of theradiator will furnish further heat. It the water is entirely with drawnand the valve 28 left open, so as to prevent the accumulation of morewater, it will be seen that the radiator is converted into anexclusively steam-heater.

By means of the peculiar connections for the steam-pipes I provide aradiator which will be neat in appearance, since all of the connectionsare hidden beneath the radiator. This construction also permits readilyapplying the invention to radiators not previously built for it.

Having thus described my invention, I

nally beneath the forward portion of the radiator, the pipe havingcommunication with the elbows, an additional pipe in communication withthe said longitudinal pipe the additional pipe communicating directlywith the lower portion of the interior of the radiator, and a valve forsaid additional pipe, substantially as described.
